[PATCH] Documentation/git-merge.txt: weaken warning about uncommited changes

[Matthieu Moy <Matthieu.Moy@imag.fr>]

Commit 35d2fffd introduced 'git merge --abort' as a synonym to 'git reset
--merge', and added some failing tests in t7611-merge-abort.sh (search
'###' in this file) showing that 'git merge --abort' could not always
recover the pre-merge state.

Still, in many cases, 'git merge --abort' just works, and it is usually
considered that the ability to start a merge with uncommited changes is
an important property of Git.

Weaken the warning by discouraging only merge with /non-trivial/
uncommited changes.

This is a followup to an old discussion:

http://thread.gmane.org/gmane.comp.version-control.git/221069

I don't think documenting all the failure cases in the doc would be a
good idea, so I've left the "in some cases" part.
